The Kingfisher and Sand Martin have lost many of their natural nesting sites where streams and rivers have been diverted, restructured or otherwise `improved`.
Our Nest Tunnel provides a vital nesting opportunity in such places, and also on natural waterways where no suitable sites are available or where apparently suitable banks are too stony or have too many roots.
This Tunnel was tested for decades and successfully used in many projects for rebuilding waterways all over Europe.
To be built into ground.
